Substantial growth in the economy and extensive use of natural resources has become a major issue in the modern world. Organizations have started to worry about the environment and are beginning to invest in and practice green strategies. Companies should be responsible for the environment and use sustainable methods to run their businesses. The main purpose of this study is to explore the conceptual approach to Green Human Resource Management (GHRM) practices and Corporate Environmental Responsibility (CER) in the hospitality industry. The theoretical framework of GHRM practices such as green recruitment, green selection, green training and development, green performance appraisal, green reward and compensation, and corporate environmental responsibility have been comprehensively studied for this purpose. Green Human Resource Management in the hospitality sector is a less studied and rarely implemented phenomenon. The integration of GHRM and CER along with green competitive advantage and green supply chain management in hospitality is new concept in hospitality industry. Study suggests that Corporate environmental responsibility (CER) and Green Human Resource Management (GHRM) have a significant role in the hospitality industry. However, for sustainable development of tourism and hospitality, this concept should be capitalized with necessary research and development.

Numerous novel marine natural products have been discovered and isolated from varied marine organisms by the diligent bio-prospectors over the past decades. An assessment of the current status of commercial development of these natural compounds indicates only minimal commercialization due to the lack of sustainable supply. To bridge the gaps between discovery and commercialization of these tantalizing bioactive compounds, marine bioprocess engineering is the key for its success. The problems, challenges and opportunities for marine bioprocess engineers are examined for the timely transformation of the discovery into commercial reality. Marine bioprocess engineers will find it the most rewarding practice of their expertise in diving into the ocean.

In the context of Sustainable development, China, the world's second-largest apparel market, is also concerned about the environmental impact of fiber waste. Currently, there is a great interest in sustainable fashion in both supply and demand in China. Based on the theory of planned behavior(TPB), the determinants of sustainable fashion consumption(SFC) of Chinese consumers were evaluated in this study: man-nature orientation(MNO) and environmental knowledge(EK) as motivation and perceived online-store accessibility(POA) and perceived money availability(PMA) as barriers. Wenjuanxing, a Chinese professional survey collection agency, conducted an online survey of millennials in Shanghai, China. The final sample size for the survey was 215. Partial least squares structural equation modeling was employed to test the proposed hypotheses. The results indicated that attitudes, subjective norms, and perceived behavioral control significantly affected the purchase intention towards sustainable fashion products. MNO and EK influenced the attitude, whereas EK, POA, and PMA influenced perceived behavioral control. This study contributes to the TPB literature through the examination of four antecedents: MNO, EK, POA, and PMA. The findings provide valuable insights for retailers and markets based on the identification of the motivations and barriers that enhance the purchasing intention of Chinese millennials toward SFC.

This study analyzes the key drivers (commitment, integration of big data, green supply chain management, and green human resource practices) of sustainable capabilities and the influence to which these sustainable capabilities impact the banks' environmental and financial performance. Additionally, this study analyzes the impact of green management practices on the integration of big data technology with operations. The theory of dynamic capability was deployed to propose and empirically test the conceptual model. Data was collected through a self-administrated survey questionnaire from 319 participants employed at 35 banks located in six ASEAN countries. The findings indicate that big data analytics strategies have an impact on internal processes and banks' sustainable and financial performance. This study indicates that banks committed towards proper data monitoring of its clients achieve operational efficiency and sustainability goals. Moreover, our results confirm that banks practising green innovation strategies experience better environmental and economic performance as the employees of these banks have received advance green human resource training. Finally, our study found that internal and external green supply chain management practices have a positive impact on banks' environmental and financial performance, which confirms that ASEAN banks contributing in reduction of environmental impact through its operations will ultimately experience increased financial performance.

기후변화는 이미 지속 가능한 수자원 관리에 영향을 미치고 있다. 기후변화가 댐 저수지의 물 공급에 미치는 영향은 일반적으로 지구 기후 모델 결과 기반으로 생성된 기후변화 시나리오를 사용하여 수행되고 있다. 그러나 기후변화를 추정하기 때문에 시나리오는 미래에 발생할 수도 있는 상황을 가정하는 한계로 인하여 본질적으로 불확실성을 내포하고 있다. 이러한 문제에 대한 대책으로 의사결정 스케일링 접근법을 본 연구에 적용하였다. 연구대상지는 충주, 용담, 합천, 섬진강 댐이다. 강우 유출 모형(IHACRES)과 HEC-ResSim기반 댐 운영 모형을 결합하여 댐 이수 안전도를 분석하였다. 이 수안전도 분석은 안정적인 댐 운영에 목적을 두고 그 결과에 따라 구조적 또는 비구조적 이수공급 계획을 수립하는데 활용하고 있다. 따라서 본 연구에서는 이수안전도 분석으로 댐이 안전하게 운영될 수 있는지를 평가하고 장래 댐 운영 중 발생할 수 있는 잠재적인 위험을 식별하기 위함이다. 1995년 부터 2014년까지 관측된 강수량과 온도를 기준으로 49개의 기후스트레스 시나리오(분위 수 기준 7개의 강수 시나리오와 0℃부터 6℃도까지 1℃ 간격의 7개의 온도 시나리오)를 적용하였다. 그 결과 홍수기 강우 변동이 비홍수기의 강우 증가보다 수위 상승에 더 큰 변화를 가져왔다. 따라서 이수 안전도는 1분위 강우 의존성이 매우 높은 것으로 평가되었다. 또한 강수 및 온도를 결합한 시나리오에서 댐 용수 공급 신뢰도는 개별 강수 및 온도 시나리오 신뢰도 변화의 합계보다 더 큰 변화가 모의되었다. 이러한 차이는 강수량의 감소와 증가가 각각 물과 에너지가 제한된 증발량의 발생으로 초래하는 것으로 나타났다. 본 연구에서 수행한 의사결정 스케일링을 통한 이수안전도 평가는 댐 운영의 효율성 향상을 도모할 것으로 평가된다.

In addition to simply providing quality food to the people, the fishery industry must be maintained and developed because it has various functions such as national food security, preservation of natural scenery, protection of national territory, and revitalization of the local economy. However, risk factors such as climate changes and environmental destruction have raised concerns about the sustainable development of the industry. Since these risk factors are becoming larger and more complex over time, it is time to conduct research related to the risk of the fishery industry. Therefore, the purpose of this study is to explore the risk factors facing the fisheries at this point, to analyze the economic ripple effect of regional fishery product supply shortage, and to draw implications. As a result of this study, the economic ripple effect of fishery product shortage per won was highest in Busan, followed by Gangwon, Gyeongnam, and Gyeongbuk. Considering the size of the local fishery industry, Busan had the highest supply shortage per 1% of local fisheries production. It is also necessary to prepare special risk management and countermeasures for these regions since the effect of supply shortage in regions such as Jeonnam, Gyeongnam, and Jeju is large compared to other regions.

골재는 일반적으로 암석이 강에서 운반되거나 인공적으로 파쇄되어 형성된 모래와 자갈 등을 말하며, 건설 산업의 핵심 자원이다. 경상북도는 전국에서 가장 넓은 행정구역으로, 산림골재, 육상골재, 하천골재, 선별파쇄골재 등 다양한 종류의 골재를 생산하고 있다. 2022년 기준으로 약 696 만m³의 골재를 채취하였으며, 이 중 허가에 의한 채취물량은 약 407 만m³, 신고물량은 약 288 만m³이다. 경상북도의 골재수요는 레미콘 공급량의 추정 방법에 따라 1,239 만m³로 나타난다. 골재의 공급 측면에서는 약 120 개의 채취장이 운영되고 있으며, 대부분의 시군에서는 골재의 수요와 공급이 적절하게 유지되고 있다. 다만, 일부 지역에서는 경상북도 인접지역에 반입과 반출이 발생하고 있다. 경상북도의 골재의 반입과 반출이 많은 지역은 경부선을 따라 경상북도 남부와 대구광역시, 포항시로 연결되는 지역이며 인구의 분포와 높은 관련성이 나타난다. 경상북도는 인구 감소와 농촌 지역의 고령화, 지역 간의 균형 발전 부족 등의 문제에 직면하고 있으며, 연구결과로 제시된 GIS를 이용하여 출발지-도착지 분석을 통해 파악된 골재의 수요와 공급 흐름에서도 이러한 양상이 확인된다. 경상북도의 골재산업구조와 공간구조를 분석한 결과 현재 경상북도는 다양한 골재원의 공급으로 수요를 충족하고 안정적인 골재 수급이 유지되고 있다. 하천골재와 육상골재는 장기적인 개발이 어렵기 때문에 단기간 공급전략으로 유지될 수 있으며, 선별파쇄를 통한 공급은 원석 공급에 의존하여 안정성 유지가 어려운 상황을 고려하여 원석관리의 필요성을 제안하였다. 경상북도에서는 골재자원의 안정적 공급을 위한 장기적인 대안으로 산림골재가 중요 자원으로 부각되어 대규모 골재 채석장 개발의 필요성을 제시하였다. 본 연구결과는 골재 자원의 지속 가능한 관리와 안정적 활용을 위한 전략 수립에 중요한 정보를 제공할 것으로 기대된다.

The green house on the waterfront is air-conditioned by a water-source heat pump system with riverbank filtration water. In order to supply riverbank filtration water in alluvium aquifer, the riverbank filtration facility for water intake and recharge, two pumping wells and one recharge well, has been constructed. The research site in Jinju, Korea was chosen as a good site for riverbank filtration water supply by the surface geological survey, electrical resistivity soundings, and borehole surveys. In the results of two boreholes drilling at the site, it was revealed that the groundwater table is about 3 m under the ground, and that the sandy gravel aquifer layer in the thickness of 6.5 m and 3.5 m occurs at 5 m and 7 m in depth below the ground level respectively. To prevent the recharge water from affecting the pumped water which might be used as heat source or sink, the distance between pumping and recharge wells is designed at least 70 m with a quarter of recharged flow rate. It is predicted that the transfer term, the recharge water affects the pumping well, is over 6 months of heating season. Hydrogeological simulation and underground water temperature measurement have been carried out for the pumping and recharge well positions in order to confirm the capability of sustainable green house heating and cooling.
